Subject: Re: Rational roots theorem

Rational root theorem: The possible rational roots of a polynomial with integer coefficients are r = p/q, where p is a divider of the absolute term and q is a divider of the highest power term coefficient. Used in the proof that the 3 famous problems of antiquity (angle trisection, doubling of a cube, and construction of a regular heptagon) as well as some new geometry problems (construction of a triangle from its angle bisectors) are impossible using a straightedge and compass.
